Requirements Definition

Author requirements, create requirements from external documents, define requirements hierarchy

Create requirements from within Simulink® through the Requirements Editor or the Requirements Browser pane in the Requirements Perspective View. Add detailed text, images, and keywords to describe requirements. Add child requirements to specify lower-level functionality. Add context to your model by showing requirements and descriptions on the Simulink canvas.

Import requirements from external applications such as Microsoft® Word, Microsoft Excel®, IBM® Rational® DOORS®, and IBM Rational DOORS Next Generation. Simulink Requirements™ also supports roundtrip workflows with ReqIF files. Revise requirements by using the Requirements Editor or by synchronizing changes from the external document.
